To aZZ whom'z't may concern: 7 I

Be it known that l, EDWARD PossoN, -a citizen of the United States, residing at Chicago, in the county. of Cook and State of Illinois, l'iave invented certain new and-use-' ful Improvements in Grain-Doors tor Cars",- of which the following is a specification.

This invention relates to doors for freight cars, and the like, and the principal object of the invention is to provide an improved grainxdoor. A further object is to provide an improved sectional grain door having improved means for supporting the sectionsv thereof in operative and inoperative posi tions' till another object is to provide a grain door having a pluralitybf sections which are'slidable in vertical guideways, in combination with improved means ior supporting said sections adjacent the door open-. ing' in positions parallel to the positions; which they normally occupy when closing the door opening. is further object is to pro- H vide an improved door section, in combina-' tion with improved bracketsior supporting the door'sections when they are displaced from normal position closing the door open ing. Another feature is the provision oi improved brackets or supporting the door sections and improved means for mounting said brackets adjacent the door openin Other objects relate to features of construc-o tion and arrangement, as will appear more fully hereinafter. A I

These and other objects of the invention] will appear more clearly from the following" saeciiication, taken in connection with the accompanying drawings, in which one enibo'diment'or' tneinve'ntion is illustrated. In the. drawings Figure 1 is a longitudinal sectional View; through a freight car, showing aside eleva ti'onoi my improved sectional grain door viewed from the interiorof the car. i V

Patent d Sept; thread;

In the accompanyingdrawings the side walls 10 otthe freight car are shown as comprising the inside sheathing 10 and the outside sheathing 10 Door openings 11- are formed in the opposite'car walls, doo'r posts l2extend ng-vertically at each edge of 'the uoor'opening, with framehiembers 18 extending between theposts at the upper,

edges of the openings. Metal plates 14 are mounted on the-floor 15 of the car, between the door posts, forming door sills. The usual purlinsl'G extend longitudinally of the car and overthe-rnembers of the door frames, having attached thereto by suitable means the purlin plates 17. Z-bars 18, at-

tached-to the outer purlin. plates, may serve asguides'or traclrs for-"the usual outside doors." The purl-ins and purlin plates serve to support the outer edges of the roof 20, and the intermediate parts of the roof are supported by transverselyextending carlines 21, which are secured at their ends to the purlins at the sides ofjthe car. The usual running board 22 is mountedabove the roof.

Each door post 12 has secured to the inner corner or edge thereof a vertically extendingshe'et metal reinforcing plate of angle i 'orm, which may besecured to the door post by nails 25, or other suitable means. A doorjamb 26 is secured to the inner sidefot thecar wall and to the adj acent door .post at each edge of the'door opening. A I sheet metal angle plate: serves to reinforce the edge of thisyamb'j which is directed,toward'the door opening,v and also 'a part of the undercut notch 28- which is formed in thei'jamb. A sheet' metal guide plate 29 is atached to each of the door jambs 26"by' means or" screws 30, or the llke, and these guideplatesseat n the notches 28 andfentend'beyond the edges 26 of the door jambs-to form guideways Slior the edges'ofithe sectional-grain door;-

The grain door consists of a plurality of .door sections] in 'theform of plates or sheaves, which are preferably formed of wooden boards 35% with'metal sheathing 35 extending entirely around them and, secured thereto. by rivets 36,.10r the like.

Each longitudinal edge of each door sec.- tion .is provided with a. notch 37:, which notches are-oppositelydisposed at the opsections.

posite edges of each door section, so that when the door sections are placed in position to close the door openings,"as shown in Fig. 1, these notches and the corresponding projections 37* will interlock with each other to form a grain-tight closure. will be understood that the vertically extending ends of the door sections are adapted to engage the guideways in which they are vertically movable, so that a grain-tight closure is formed along the vertical edges of the door, as well as between each pair of door When the sections are in doorclosing position, as shown in Figs. 1 and 3, the longitudinally extending projection 3'? on the lowermost section is adapted tooverlap the inner edge of the doorsill or plate 14 adjacent thereto, so that a grain-tight closureis .also formed along the'lower edge of the door opening. It will be seen that the reinforcing plates Qe'and 27 serve, with the plates 29, to form durable guideways which will not become materially worn after continued use. a

One or more of the door sections 35 is provided at each end with apertures which are adapted to aline with corresponding apertures 29 and 12, formed in the guide plates 29 and door post, respectively, so that pins 40 may be passed through these alining apertures to secure the door sections in fixed position closing the corresponding door opening, These pins may be attached to chains 41, which are connected to suit able staples as engagin the car wall.

Each of the door sections is provided with a pair of hand holes or depressions 4:23 on the outside thereof, and a corresponding pair l3 on the inside thereof, these depressions being diagonally disposed on opposite sides of the door, and having the metal sheathing 85 pressed into them. These hand holes be engaged by the fingers of the operator to move the corresponding:

door section vertically in the guideways in order to open the grain doors. ing is effected by moving the sections successively in the guideways until they have passed to such-positions at the upper end of the guideways that they may be displaced horizontally to besupported in the door section holders or brackets 45. l

Each of the brackets is preferably formed oisheet metal, andcomprises a main wall or end plate 4-5? adapted toengage the ends of the doorsections, a verticallyextending.

longitudinally-directed flange 45 adapted to engage the vertical edge of? the innermost door section when. the door sections are supported therein, a horizontal l adapted to engage and support the lower most edges of the door sections, and 4C5 directed toward the end of the car and which is adapted to be secured. to the adjacent purlin and, door, post, between said This openmembers and the door jamb, which is partially out awayto receive the flange. Each of the flanges a5 is provided with a plurality of'apertur es adapted to be engaged by screws 46, by means of which the bracket ets, and riveted, or otherwise secured, to the. The,

vertical flanges 45 of the brackets. portion of each flange 4L5 adjacentthedoor opening is bent upwardly to form a lug or:

flange 45 adapted to engage theedge of the last door section to be placed in the bracket, in order to prevent displacement of the door sections from the. brackets into the guideways. Each bracket also comprises a. transversely-extending guiding and retaining flange 45 formed on the upper part thereofand directed toward the opposite side 01 the door opening:- These last named flanges areinclined inwardly and downwardly,as shown particularly in Figs. 3 and 5, the

space between the inner extremities of these,

flanges and the horizontally -extending .flanges 415 being substantially equal to the vertical dimensions of the door sections. The outer extremities of the flanges LS are spaced above the upper extremities of the flanges 45* a distance which is also slightly greater than the vertical dimensions of the door sections, so that when the sections are passed upwardly in, the guideways they may be displaced horizontally from the upper ends of the guideways between the flanges 45 and the innerextremities of the flanges 4:5, and then moved horizontally into thebrackets, by which they are supported in inoperative positions. ,Allofthe flanges are preferably formed integrally with thebody portion 45 of the bracket. Y

The upper extremities ot the verticallyextending flanges 45* are secured tothe longitudinally extending rpurlins or frame members 48, which underlie the roof of the.

car and are attached to the transversely-extending carlines .21. It will be seen that these carlines are secured against relative displacementby means of the tie rods 49. In

this manner the brackets 45 are rigidly sup ported in position adjacent thecar roof near the upper edges of the'door openings, and" 1t will be seen that the outermost parts of I the brackets form continuations of or cornmunioate with the guideways 31, so thatfthe door sections may be passed directly into the brackets, by which they are supported when not in use. .A. sufficient number of door sections may be provided to close the door opening, orflto close the opening with exception ofa small space adjacent the permit displacement of sections over said lugs and to prevent displacement of the innermost section upwardly from said horizontal parts;
